To proceed efficiently, we kindly ask you to send us the following information and documentation per email:

  • A good quality photograph of your art object
  • Name and informationabout the artist (if known)
  • Title of the object
  • Signature and/or attribution 
  • Material, technics, measurement and weight
  • Condition of the object (need reparations or not etc.)
  • Existing expertises (if available) or certificates for jewellery
  • Provenance

Based on this information our experts will contact you. For bigger collections or objects of a significant value, our experts will be happy to visit you if you prefer us doing so.


Once you’ve decided to sell your objects through our house, we’ll define an estimate as well as a limit price in common agreement.


An oral valuation is free of charge and is without engagement for both parties.

If an auction contract comes to be concluded, our experts will precisely and professionally study your objects to describe them in our catalogue. From this moment on and until the end of the auction, the objects will be stocked on our premises. Before the auction, our clients receive the final contract with the estimated price range and the limit.

If you do not desire to sell your objects through our auction house and we have made a written estimate, we’ll allow us to charge you the expenditure for our work.




The consignment deadline for our Spring auction is mid-March, and for our Autumn auction, it is mid-September.

The transport costs of the objects are on the client’s fee. We can help you organize the transport with a specialized company. In particular cases and if we are in your region, we can collect your smaller items.


By receiving your objects in advance gives us enough time for detailed research and an attractive presentation in our catalogues.





Once your objects are in our house, they are fully insured. Insurance of unsold objects is valid up to 60 days after the last day of the past auction. It’s prolonged if the objects are re-offered in a future auction.




The legal base of your consignment is the auction order/contract. By signing it, you give Stuker the right to auctioneer and to sell your items to the highest bidder. At the same time, you confirm being the legal owner of these objects.




An estimate (low and high) is a value range for which your object might be sold on the actual international art market. It is established by our experts and with your agreement. These low and high estimates are published in our catalogues.

The reserve price is a minimum price (before the deduction of our commission and the VAT taxes) for which you agree to sell your objects. 

  • If we have an agreement on a fixed reserve price, we engage us not to sell your objects under this price.

  • If we have no agreement on a fixed reserve price, we principally don’t sell lots under the half of the highest estimate.

The reserve price is confidential information agreed between the consignor and Stuker. The reserve price is usually set near or below the low estimate published in our catalogues.




All lots can be viewed in our premises during an eight-day-presale-exhibition. At this occasion, a large circle of art connoisseurs from Switzerland and abroad visits our house.

Our printed catalogues are appreciated for their quality and beautiful design. They are widely distributed to our clients and can be ordered free of charge. An online version of the catalogue and a Pdf-Version can be viewed or downloaded from our website some weeks before the auction.


During the auctions, our clients can personally place their bids in the salesroom but they can also bid by writing a buyer’s order, by requiring a phone bid or by bidding online through the international platform The lot is sold to the buyer with the highest bid.



The hammer price is the winning bid for a lot during an auction. Our seller’s commission and the VAT are to be deducted from the hammer price.



The seller’s commission for the auction house is to be deducted from the hammer price. This commission is a payment for auction’s services and usually amounts to 20% of the hammer price including cataloguing costs, photographs, insurances, storage costs, as well as costs for advertising, exhibition and auction.





The value-added tax (VAT) is added – according to the actual regulation – to the seller’s commission. It’s clearly and separately stated on the bill.



Auction results are published on our website. Payment is due six weeks after auction date, under the condition that the buyer has entirely paid his or her acquisition. The amount due by Stuker is transferred to you according to your instructions, usually to your bank account.




Stuker has the right to sell unsold lots at a previously agreed price up to two weeks after the auction has taken place.


Upon supplementary agreement with the auction house, the unsold objects can be re-offered in a future auction.
